Where are MXenes closest to real-world use?
MXenes are closest to practical adoption in applications that exploit their high electrical conductivity and large surface area, particularly electromagnetic interference (EMI) shielding and energy storage. For EMI shielding, MXene composites achieve a shielding effectiveness of ~57 dB at an ultra-thin thickness of 0.009 mm, which is competitive with or better than many commercial materials [7]. This means a very thin coating can block over 99.999% of electromagnetic radiation, making it attractive for electronics and military applications.
In energy storage, MXene-based electrodes have demonstrated high capacity and stability. For example, a composite of polyoxometalate nanoparticles bonded on MXene nanosheets delivered a capacity of 297 mAh/g for lithium storage and 191 mAh/g for sodium storage at 1.0 A/g, even after 1000 cycles [3]. This performance, combined with high capacitive contributions (81.6% for lithium), suggests MXenes could enable faster-charging batteries and supercapacitors. A 2025 feasibility analysis concluded that optimized acid etching and post-processing methods can achieve high-yield, reproducible MXene synthesis, making industrial-scale production both technically feasible and economically viable [2].
Where do MXenes still fall short of industrial requirements?
For transparent conductive electrodes (TCEs) used in touchscreens and displays, pure MXene films currently fail to meet industrial standards. A 2025 study analyzing published data found that even the best continuous Ti3C2Tx MXene films have a DC-to-optical conductivity ratio of ~24, which is below the minimum requirement of ~35 for commercial TCEs [5]. However, by integrating a metallic silver grid with the MXene film, the ratio jumped to 330, far exceeding the requirement, showing that hybrid approaches can bridge the gap [5].
Long-term stability and scalability remain cross-cutting challenges. MXenes are susceptible to oxidation, which degrades performance over time [6]. Restacking of nanosheets reduces active surface area, and achieving consistent large-scale production with controlled flake size and quality is still difficult [4][2]. A 2021 review noted that aggregation of MXenes can reduce adsorption activity and surface area, and that environmental risks and toxicity need broader evaluation [9]. These issues are being actively addressed, but they delay adoption in applications requiring long lifetimes or strict safety standards.
What needs to happen for MXenes to reach widespread adoption?
The path to widespread adoption requires solving three key problems: scalable synthesis, long-term stability, and application-specific optimization. A 2025 feasibility study provided a practical framework for industrial-scale MXene production, showing that with optimized acid etching and post-processing, high-yield synthesis is achievable and cost-effective [2]. This bridges the gap between lab-scale and commercial production.
Stability improvements are also critical. Strategies like forming composites with polymers (e.g., chitosan) or metal-organic frameworks (MOFs) can enhance performance and durability. For example, MXene/chitosan composites show promise in EMI shielding, water treatment, and energy storage, but challenges in long-term stability and cost-effective manufacturing remain [1]. Similarly, MXene-based nanozymes (MXenzymes) offer advantages over natural enzymes in stability and tunable activity, but need more mechanistic studies and scalability work before real-world use [6].
Machine learning is accelerating the discovery and optimization of MXene properties. A 2024 study used graph neural networks to predict key properties like work function, bulk modulus, and magnetic behavior with high accuracy (e.g., root mean square error of 0.418 J for work function) [8]. This can dramatically reduce the time and cost of screening new MXene compositions, helping to identify the best candidates for specific applications and speeding commercialization.
